Ukuphonswa kwedayi ngokunemba okuphezulu kuyinqubo ebalulekile embonini yokukhiqiza, edlala indima ebalulekile ekukhiqizweni kwezingxenye zensimbi eziyinkimbinkimbi. Le ndlela yokukhiqiza ethuthukisiwe ihilela ukufaka insimbi encibilikisiwe esikhumbeni sensimbi, esaziwa ngokuthi idayisi, ngaphansi kwengcindezi ephezulu. Umphumela uba ukudalwa kwezingxenye ezisezingeni eliphezulu, ezinesilinganiso esifanele kanye nokuqedwa okuhle kakhulu kwendawo. Inqubo yokuphonswa kwedayi isetshenziswa kabanzi ezimbonini ezahlukahlukene, kufaka phakathi i-Automotive, Izindiza,Ukuxhumana ngocingokanye nokukhiqizwa kwemishini yezokwelapha.
Enye yezinzuzo eziyinhloko zokwenziwa kwe-die casting ngokunemba okuphezulu yikhono layo lokukhiqiza izingxenye ezine-tolerances eqinile. Leli zinga lokunemba libalulekile ezimbonini ezidinga izingxenye ezine-geometri eziyinkimbinkimbi nemininingwane emincane. Le nqubo ivumela ukukhiqizwa kwezingxenye ezinezindonga ezincane, amakhona abukhali, nezici eziyinkimbinkimbi, okwenza kube ukukhetha okuhle kakhulu kwezicelo lapho ukunemba kubaluleke kakhulu.
Ukunemba okuphezulu okutholakala ngokuthungwa nge-die casting kubangelwa ukusetshenziswa kobuchwepheshe obuthuthukisiwe kanye nemishini yesimanje. Isofthiwe yokuklama ngekhompyutha (CAD) kanye nokukhiqiza ngekhompyutha (CAM) isetshenziselwa ukudala izikhunta ezinemininingwane eminingi eziphinda ngokunembile i-geometry yengxenye efiselekayo. Ngaphezu kwalokho, ukusetshenziswa kwemishini yokuthunga nge-die casting ethuthukisiwe enezinhlelo zokulawula ezinembile kuqinisekisa ukuthi insimbi encibilikisiwe ifakwe ku-mold ngokunemba okungavamile, okuholela ezingxenyeni ezihlangabezana nezindinganiso zekhwalithi eziqinile kakhulu.
Ngaphezu kwalokho, ukuphonswa kwedayi okunembile okuphezulu kunikeza ukuphindaphindeka okuhle kakhulu, okusho ukuthi izingxenye zingakhiqizwa njalo ngokushintshashintsha okuncane kusuka kwelinye ibhetshi kuya kwelinye. Leli zinga lokuvumelana libalulekile ezimbonini lapho ukufana nokuthembeka kubalulekile khona. Kungakhathaliseki ukuthi kukhiqiza izingxenye ezincane noma ezinkulu, ukuphonswa kwedayi okunembile okuphezulu kuqinisekisa ukuthi ingxenye ngayinye ihlangabezana nezidingo ezibekiwe, okuholela ekuthuthukisweni kwekhwalithi yomkhiqizo kanye nokusebenza.
Ngaphezu kokunemba nokuphindaphindwa, ukuphonswa kwe-die okunembile kakhulu kunikeza nezixazululo zokukhiqiza ezingabizi kakhulu. Amandla okukhiqiza izingxenye eziyinkimbinkimbi ekusebenzeni okukodwa anciphisa isidingo sezinqubo zokukhiqiza zesibili, okuholela ezindleleni zokukhiqiza eziphansi kanye nesikhathi esisheshayo sokuya emakethe. Lokhu kwenza ukuphonswa kwe-die okunembile kakhulu kube inketho ekhangayo yezinkampani ezifuna ukwenza lula izinqubo zazo zokukhiqiza nokuthuthukisa ukusebenza kahle kokukhiqiza.
Ukuguquguquka kokwenziwa kwe-die casting ngokunemba okuphezulu kudlulela ezinhlobonhlobo zezinto ezingasetshenziswa, kufaka phakathi i-aluminium, i-zinc, i-magnesium, kanye ne-alloys esekelwe ethusi. Izinto ngazinye zinikeza izakhiwo nezinzuzo ezihlukile, okuvumela abakhiqizi ukuthi bakhethe i-alloy efaneleke kakhulu ngezidingo zabo ezithile zohlelo lokusebenza. Kungakhathaliseki ukuthi izingxenye ezilula embonini yezimoto noma izingxenye ezingagqwali zomkhakha wezindiza, ukwenziwa kwe-die casting ngokunemba okuphezulu kungahlangabezana nezidingo zezinto ezahlukahlukene.
Njengoba izimboni ziqhubeka nokufuna ikhwalithi ephezulu kanye nezingxenye eziyinkimbinkimbi kakhulu, indima yokwenziwa kwe-die casting enembile kakhulu ekukhiqizeni kwesimanje iya ngokuya iba yinto ebaluleke kakhulu. Amandla ayo okukhiqiza izingxenye eziyinkimbinkimbi, ezisezingeni eliphezulu ngokunemba nokusebenza kahle okumangalisayo kwenza kube yitshe lesisekelo lezinqubo zokukhiqiza ezithuthukisiwe. Ngokuthuthuka okuqhubekayo kwezobuchwepheshe nezinto zokwakha, ukwenziwa kwe-die casting enembile kakhulu kulungele ukuhlala kuyimbangela eshukumisayo ekukhiqizweni kwezingxenye ezisebenza kahle kakhulu ezimbonini eziningi ezahlukene.
